Bonsoir,
Not sure if I should fill a bug report, because I learnt that my bugs
could kill other apps :-(
Does anybody here have tips on how to track at-spi related bugs ?
I'm tracking eog and it segfaults when I close the app.
I think it's while receiving an
"object:property-change:accessible-name"
of a dying Accessible. I might be taking to much time to retrieve the
"Actions"
<wild gess>
AccessibleAction* action=Accessible_getAction(acc.legacyPtr());
long nbActions=AccessibleAction_getNActions(action);
actionNames_.reserve(nbActions);
actionDescriptions_.reserve(nbActions);
actionKeyBindings_.reserve(nbActions);
for(long i=0; i<nbActions; ++i){
actionNames_.push_back(get_string(action, AccessibleAction_getName,
i));
actionDescriptions_.push_back(get_string(action,
AccessibleAction_getDescription, i));
actionKeyBindings_.push_back(get_string(action,
AccessibleAction_getKeyBinding, i));
}
AccessibleAction_unref(action);
}
</wild guess>
It's hard to be sure, because eog segfault, not my app :-(
Now, I am ready to accept help because I am, at last, running CVS
Gnome compiled with debug symbols, so I can give meaningful debug
info.
Any help greatly appreciated !
Bernard
PS: attached backtrace of eog
